l vention will hereinafter appear and the 1 -novel features thereof will Vbe partlcularly Other objects andadvantages of the inpointed out in the appended claims'.

The invention is clearly illustrated inthe accompanyingV drawings which, with the numerals of reference marked thereon, form a part of this specication and in which:

Figure 1 is a face view of 'a Water gage constructed in accordance with my invention Fig. 2 is a substantially central longitudi- V nal section through the same, as on the line 45 2-2ofFig.l;

Fig. 3 is a cross-section, as on the line Fig. 4 is a view similar to 3 show-` ing the relation of the parts after the compressible Washer has been compressed.

' Like numerals ofreference indicate like parts throughout the several views.

Referring to the drawings: f1 designatesa casing, preferably of metal,

having a curved extension 2 and a passage1 useful ,improvements r'il vate. gagef ff that' l8 is the sight-glass. It isinsertedwithinthe casing 1, resting upon the ygasket or yare countersunk as seen at 23 to lreceive the way 3L- fr @miauw-ion gf @emigrare- 1 "The haar; allY o ftlhachamt is essere# 75 coated on'provided, Withf'a linin'gv',

dawahmgs unen parasite .Sdeatheireef as :Sherman Washer 13,V andis itself offset at Vopposite sides as shown at 19, forming v horizontal shoulders upon which -the eompressible gasket or gaskets 20 may be supported. These osets,fas'W-ill be noticed upon reference to Figs. 3 and 4, are arranged opposite the longitudinal grooves or channels 16 in the adjacent Walls ofthe casing.

i 21 is the cover or frame lovwhiehthe` sight-glass is retained in place and by means of which the gaskets or packing 20 may be compressed. This, cover or frame 'is provided with lugs 22 the upper faces of which 100 heads 24 of bolts 25. Inr assembling the'parts the gasket or Washer 13V is, placed inposition upon the shoulders 11 and 12 and then the sight-'glass 18is placed Within'the casing,` resting upon said gasket. Next the gasket or. compressible packing k20 is placed in position uponV the shoulders of the sight-glass,l and thenV the frame or cover 21 isplaced in position with its depending flange `26Y resting upon the compressible gasket or packing 20, as seen in Fig. 3. The bolts 25 are then applied, the heads 24 thereof engaging in the sockets 23 of the lugs 22, and nuts 27 are applied to their threaded ends and turned up until the parts are brought from the pov f sition in which they are seen in Fig. 3 into the position in which they are seen in Fig. 4. As pressure is applied the compressible packing 20 is gradually compressed until portions thereof are forced outward into the grooves or channels 16, as seen at 28 in Fig. 4:. The forcing of this compressible packing outward into these channels or grooves serves to more securely safeguard against leakage so that all possibility of any leak is avoided.

Upon reference to Fig. 4 it will be noted that the depending portion of flange 26 of the cover or frame 2l is of such length that when the packing 20 is compressed as shown in said ligure the shoulders 29 at the under sides of such vdepending portions 26 are still out of Contact with the adjacent face 30 of the casing 1 so that the provision is left for compressing the packing fa-151..:` should occasion arise.

The sight-glass in devices of this character occasionally gets broken, from one cause or another, and in order to prevent injury from the flying pieces of glass and to retain the glass within the casing and frame, I provide said frame with inwardly extended lugs 31, as seen in the different views, said lugsbeing arranged upon opposite sides and at each end of the inner walls of the Jframe. By this means should the glass become broken the lugs 31 will serve to prevent the glass being blown out as will be readily understood.

What I believe to be new and desire to secure by Letters Patent, is

1. In a Water-gage, a casing, a sight-glass therein, and a sight-glass retaining frame having inwardly projecting lugs adapted to extend over said glass, said lugs being positioned in the frame so as to be raised above the face of the sight glass.

2. In a water gage, a casing having side Walls provided with grooves upon their inner faces, a sight-glass within said casing and offset at its opposite edges, a compressiblepackingin said offsets, said packing beingconned in the groove formed by the offset of the glass and means for retaining said sight-glass in position and compressing said packingv into said grooves.

3. In a water gage, a casing having side walls provided with grooves upon their inner faces, asight-glass within said casing and offset at its opposite edges, 'a compressible packing in said offsets, said packing being confined in the 4groove formed by the oifset of the glass and means for retaining saidy sight-glass in position and compressing said packing into said grooves, said glass retaining means having projections extending over the glass.

In testimony whereof I aiiixmy signature in the presence of two witnesses.
